摘要

The J ülich E lectric D ipole Moment I nvestigations (JEDI) Collaboration is developing tools for the measurement of permanent E lectric D ipole M oments (EDMs) of charged, light hadrons in storage rings. While the Standard Model prediction for the EDM gives unobservably small magnitudes, a non-vanishing EDM from 𝒞 𝒫 violating sources beyond the standard model can lead to a tiny build-up of vertical polarization in a beforehand horizontally polarized beam. This requires a spin tune modulation by an RF dipole without any excitation of coherent beam oscillations. In the course of 2014, a prototype RF E × B dipole has been successfully commissioned and tested. We verified that the device can be used to continuously flip the vertical polarization of a 970 MeV/c deuteron beam without exciting any coherent beam oscillations.
